Full OpenBSD 6.9 Startup described.

#system #boot

In this guide we're going to take a look at how we can use cheap and "low end" hardware to build an amazing OpenBSD router with firewalling capabilities, segmented local area networks, DNS with domain blocking, DHCP and more.

We will use a setup in which the router segments the local area network (LAN) into three separate networks, one for the grown-ups in the house, one for the children, and one for public facing servers (a DMZ), such as a private web server or mail server. We will also look at how we can use DNS to block out ads, porn, and other websites on the Internet. The OpenBSD router can also be used on small to mid-size offices.
